serverExecutablePath is set to.. but it doesn't exist (improve config option description/error message)

[andrewufrank]

After much trying, it seems to work. Error message is not helpful, path given is not working.
Probably nothing crucial, just annoying and a loss of time.
I look forward for the IDE to work 'out of the box'

Your environment

Output of haskell-language-server --probe-tools or haskell-language-server-wrapper --probe-tools:

haskell-language-server-wrapper --probe-tools

same response with haskell-language-server-8.10.4

Which lsp-client do you use: vs-code with Haskell 1.2.0

Describe your project (alternative: link to the project):
it is the new project produced by stack new project. nothing changed but added the hie.yaml and the .ghi file

Contents of hie.yaml:

  stack:

produced manually, not automatic

Steps to reproduce

I get the notification;
serverExecutablePath is set to /home/frank/.local/bin/ but it doesn't exist and is not on the PATH

but this directory exists.
If I leave the Executable Path blank (because the executables are on the PATH) and restart vscode then the HLS seems to work.
(i.e. I can do code evaluation

Expected behaviour

no error message, because the path is correct.

Actual behaviour

Include debug information

Execute in the root of your project the command haskell-language-server --debug . and paste the logs here:

the haskell-language-server is not found, only the haskell-language-server-8.10.4. Is this perhaps the cause of the problem?

Hi, i am reading the nice bug report:

I get the notification;
serverExecutablePath is set to /home/frank/.local/bin/ but it doesn't exist and is not on the PATH

serverExecutablePath should point to the executable itself, and not the directory containing it so /home/frank/.local/bin/haskell-language-server might work

Feel free to reopen the issue if that suggestion does not fix it for you

Thank you for the explanation which helps understand what happend. Could you perhaps clarify the error message and perhaps fix the automatic setup. Starting to use an IDE is VERY complex for a new user of this IDE and subtle errors - user generated, caused by differences in set-up, etc. - are many. It is easy to discourage potential users...
I appreciate the effort and the time which goes into a tool like HLS!

Totally agree, serverExecutable should make clear it must be the full path to the executable and the error message should take in account user could set a directory instead an executable
I am gonna move it to the vscode extension (where the config option label/error message belongs to) and reopen
